Oh Laura, I am so sorry to hear Amy's not doing so hot. You know that we (you and I) don't know each other at all really, but for some reason Amy always sticks in my mind. I think it's because we suspect our Abby has a slight CH issue as well. Her back legs are so uncoordinated. (Our vet doesn't agree.) I surely hope your vet can board Amy (and a playmate) for a reasonable cost so you have some peace of mind while you're off on the boat. In my mind, the important thing, which you already said, is quality versus quantity. I know you will do what is best for Amy. Hugs !!
